Cumulative head injuries seem to have a connection to later in life brain issues.
We know a young man the age of our sons, 50 something. He played baseball with them, later was a great football player and an excellent wrestler.
He played pro football and suffers from severe brain issues, and has been diagnosed with dementia and probable alzeheimers.
So McCain may be one of the severely brain injured guys.
That does not entitle him to be a severely mentally damaged $inator. Who can be manipulated into sedition/treason.
Yep......he has definitely past his sell-by date.
